3a58b2fb2f bdev/ocssd: append command
This patch adds support for the append operation.  The user doesn't need
to specify the exact location of where the data should be placed, but
only need to pass starting LBA of a zone to append to.  The user can
retrieve the address the data was written at during completion callback.

1ad438311e bdev/ocssd: request resubmission
If a spdk_bdev_io cannot be completed, because it is sent to a zone that
is currently busy, reschedule its submission.  This mechanism will be
used by appends, as mutliple append commands can be directed to the same
zone at the same time.

ffd53b6bad bdev/ocssd: update write pointers
Update write pointers during successful write / reset completion.  This
is needed in order to support the append operation.

This patch also introduces the zone busy flag, which makes sure only one
write (or reset) operation can be active at a time.  If a request is
directed to a zone that is already processing another operation, it will
be completed with a failed status.

ba4b326cda bdev/nvme: per-namespace config_json callback
Added per-namespace config_json callbacks, so that each namespace can
dump its own configuration.  This is a nop for regular NVMe namespaces,
but it will be used by Open Channel ones to save their bdev configuration.

The callbacks are executed after controller configuration has been
saved.  This ensures that when a config is loaded, any namespace related
RPC calls (e.g. creating bdevs) are run after associated controller has
already been attached.

0468ce5343 bdev/nvme: mark controllers used by bdev_ftl
Currently, the controllers managed by bdev_ftl are skipped in
bdev_nvme's config_json output by verifying if they support Open
Channel.  Since new bdev_ocssd also uses Open Channel controllers and
it relies on bdev_nvme's config_json, additional flag was added to mark
that a controller is used by bdev_ftl.

This is a temporary solution that should be removed once bdev_ftl
becomes a virtual bdev and starts using bdevs instead of NVMe
controllers.

 rpc.py bdev_nvme_attach_controller -b nvme0 -a 0000:00:04.0 -t pcie
 rpc.py bdev_ocssd_create -c nvme0 -b nvme0n1

creates Open Channel controller nvme0 and OCSSD bdev nvme0n1 on top of
it.  The bdevs can be deleted either by the bdev_ocssd_delete call or by
deleting whole NVMe controller, in which case all bdevs are destroyed.

on an SSD that is not populated with bdevs in the

169e19c320 bdev/nvme: add nvme_ctrlr_populate_namespace_done()
This is in preparation for making this code path
asynchronous.  For now we will just call this function
immediately after calling the per-ns-type populate
namespace function.

When doing a controller reset on an nvme bdev, we should always use the
bdev_nvme_reset function which ensures that we destroy all of the I/O
qpairs before performing the reset. This prevents us from performing a
reset and leaving the I/O qpairs in a disabled state preventing I/O from
being processed.

f57b098e7c bdev_nvme: add synchronization to reset.
The generic bdev layer currently has a lot of snychronization built into
spdk_bdev_reset. However, in a couple patches I am going to introduce a
few instances where I call bdev_nvme_reset directly from this module.
The reason I call bdev_nvme_reset directly from this module is so that I
don't have to open a descriptor to the bdev in the module itself.

In order to be able to call bdev_nvme_reset from both this module and in
response to a bdev_io, we need to synchronize and queue reset requests.
